An innovative and advanced Guide bush system developed by Star that has realized trouble-free operation with unprecedented speed and precision.

In former times, operators had difficulty managing the variations in bar diameters. The revolutionary system provides a system that is pneumatically controlled to grip both ground or drawn bar stock within a 30 micron tolerance.

* No longer is it necessary to adjust guide bushes or for the control to overcome the problem.
* No longer is it necessary to constantly measure bars and adjust accordingly.
* The rotary magic guide bush is at all times controlled by constant air pressure.
* The clearance between the guide bush and the material is always at zero.
* The guide bush system automatically adjusts to suit the material size.

Model applicable Type of guide bush

Neither control administration of material diameter nor G.B adjustment needed

Just until now

* For small diameter material in particular, it was necessary to make selection by measuring diameters of material by micrometer beforehand.
* It was also necessary to make adjustment of guide bushing at each time of introducing a different batch of material.

From now on
Guide bushing is all the times fastened tight by constant air pressure.

* The clearance between guide bushing and material is always kept nil, even when material diameter changes.
* Drawn material, if diameter dispersion is within 0.03mm, can be used.

Setting method

* Turn the air pressure OFF and tighten the adjusting nut to such an extent that the material can be moved in and out lightly by hand.
* Next, turn the air pressure ON and adjust the pressure while putting in and out the material by hand. Setting is thus completed.
It is as simple as that.

*Even for machining drawn bar stock (tolerance within 0.03mm), same precision as that for ground bar stock is available. Material cost can be greatly saved.
